A solids transfer mechanism is described for transferring solid chunks from a sealed chamber to a receiver. The solid chunks are transferred from a sealed cavity into a larger volume dump cavity from which they are dumped into a receiver. By use of a larger volume for the dump cavity, contact between the seals and the solid chunks is minimized, since the chunks are loose inside the larger volume dump cavity.
